been editing various formats in premiere, different sequences depending on res and frame rate, all fine on output on most vids, i just select match sequence settings before exporting and it mostly exports everything to mpeg with really huge file sizes,
some issues though, queries, questions...
when using any bluray footage it always outputs to mpeg2, wanting to know if there is any loss of quality on output, media info shows the datarates to be the same, the video quality looks the same,
should i always use match sequence settings?
with loading wmv files i had to setup a custom sequence as cant seem to find the wmv sequence, this is strange as it now seems i have to reencode to f4v after editing, this seems to be a good codec to decrease file size somewhat, again i use match sequence settings when using this codec, how does this rate comparatively, are there other output options i should be considering?
everything is taking extremely long time to output, pretty much from what ive been advised prior, i need a gcard that has mercury playback to get this to load easier and encode quicker? what kind of differences should that make?, in indexing and conforming it will make a great difference aswell right?
also with some other settings, just confirming field order should be progressive for dvd bluray and all other internet video?
upper or lower for interlaced, which one for the interlaced footage?
also have optimising rendering performance to memory for maximum bit depth setting.. obv,
hope i can get some assistance, cheers

Yes there is quality loss. It's re-encoded , so you incur 1 generation of lossy encoding. Even MPEG2 source blu-ray is re-encoded. PP doesn't smart render MPEG2 without external plugins, and most blu-ray sources are AVC these days

it seems with wanting to output the wmv with the same quality or minimal quality loss and of similar file size this can't be done. i still dont know how to set the output options correctly, always seems either a massive loss of quality or fine quality and a 4gig 45 min mpeg2 output, what should i be setting it too, ive tried flv with matching sequence settings but it still wants me to add the bitrate, if i set the 600k or 800k from the source and encode the quality is terrible. what is my best output option with minimal quality loss and maintaining a similar file size
-
just set it to 4mb flv as a custom output, and although the file size is comparable, the quality isnt, checked bitviewer, image below,
shows the original wmv on the left, and the 4mb output of flv, same res and frame rate, similar file size output;,

what do i need to output this to for minimal file loss? a higher data rate obviously but then it will give a much larger file size, is there any other option, what is my best way of outputting not only this but other formats that have a higher than 25mbps data rate, 30mbps etc, what are my output options considering this,Last edited by krohm; 9th Jun 2011 at 04:14.

either bite the bullet, or use a higher bitrate
probably I-frame h.264 using x264, using fast decode settings would be easy to edit and decent filesize
or use a proxy / offline edit workflow (swap in the high quality versions on final render) -
atm im using match sequence settings, and it gives large output files but the quality seems comparable to the original, is this my ill informed inexperienced video eyes talking,
it seems i need a new output 'workflow' right? or is using match sequence settings is fine if i dont care about file sizing? i can just store all the mpegs whereever, and than compile all of them together and trim them, edit them together etc, into a final project, and it will all be just one generation loss from the original formats, how different will it be? from there i just output again , which i assume will again incur quality loss, a second generation of loss, to convert this mpeg final product to mkv mp4,?
this or i need a way to work with the material losslessly, before outputting to mp4 mkv etc etc. and is this able to be done losslessly? or is this where avisynth comes in, to use it to allow importing all formats to premiere, and outputting losslessly to whatever container/res ild like, what steps am i missing here, i need all the material edited up and outputted before i can put it all together to create the final product. so i need outputted material to work with, hope this is somewhat understandable...Last edited by krohm; 22nd Jun 2011 at 13:54.

It's not a problem with Premiere; it handles many formats like Vegas. You can throw everything on the timeline as well. I should know, because I use both.

but i will need to output to a lossless codec (huffyub, ut or lagarith) while clipping up all the video first, create all the clips losslessly first, ?? then..
edit up all the clips into one final master project to output again losslessly and then encode with ripbot or something to whatever formats (bd, mkv, mp4 etc)
so this is the workflow i would be needing...?
im updating my pc, finding out whether i will need to change over motherboard ram and cpu aswell as graphics card, or just replace my graphics card to allow for real time editing. obviously will need more hd space, thats no problem. running premiere pro (and windows) on a ssd drive and outputting to another ssd drive is a lot faster than outputting to a sata drive yes? -
There is more than 1 way to do things
You should be able to edit everything as is, then output to some master format. If you only have 1 format to export, then use that final format instead of the mater

what if i have thousands of clips from 100s of sources, premiere would be sourcing terrabytes and terrbytes of source material...
-
so obv i need this new system to be able to work competently with this material, so i will be able to load 25gb bluray files, and have 100s of clips from these blurays, +other media, to premiere with a new system, and it will all render in real time, with no bs... then i just need to work out a way to output the master losslessly, rather than clipping up everything first...
-
tssniper wont allow me to frame accurately edit and have the control i have in premiere to be able to edit exactly the scene/clip im after, by the frame
so im wanting to be able to output these final edited clips losslessly, ready for easy insertion into the master with no editing required.
thats why it would seem it would be best to make the rough edits lossless, then i can bring them back into the project later rather than dealing with so much data and not outputting anything at all, thats not an option as i need to see how it plays etc,
how can i go about outputting them losslessly with premiere?
if i want to output to lagairth or huffy ill be able to do so quickly with new system, so could just be outputting losslessly as i go through all the material, and then collaborate all of that material at a later stage.
atm premiere outputs match sequence settings mpegs, but if i do it this way obviously will incur a second generation loss when outputting the master, and then a third when outputting to other formats. if i work with lagarith or huffy for all clips, there would be only the loss from the master to outputting to the other formats, what type of differences are there...
ive tssnipered a clip from a bluray source,
http://www.mediafire.com/?11rwpkkah7bijdd
and this is how the same edit of the source, outputted to mpeg match sequence settings for premiere,
http://www.mediafire.com/?3jsjs3hj9ta8c2b
there is a noticeable difference, so if im putting that clip back in and i output again, its just incurring more quality loss.. what type of workflow am i going to need, am i going about this the wrong way, any further feedback appreciated -
There's many ways to do this, but that's probably not the "right" way . You want rough cuts with "handles" on both sides, otherwise you won't be able to do transitions properly . You do your frame accurate cuts , timing , and transitions in premiere.
If you're just putting clips end to end, not effects or transitions or "real" editing, premiere is way overkill for this. Just put it together in avisynth. A+B+C+D etc....

I haven't looked at this, but MPEG2 is lossy. If you use high enough bitrates (e.g. 100Mbit/s for long GOP, 250+ Mbit/s for I-frame), then it's close to visually lossless. You are also incurring colorspace losses if you add transitions, effects. Y'CbCr is converted to RGB. Once you're in RGB , stay in RGB until the final format . If you're worried about it use something else truly lossless, or a "pro" DI format like cineform or dnxhd -
yeah i will be needing handles on either side, but mostly i cut an entire scene and i will only be using a part of it, so can just rough cut entire scene that has the footage im after, output that losslessly, and then when all the material is together i can start to storyboard it before doing the editing process. not sure if this is the best way to go about it, but it seems like it from my perspective, which admittedly is somewhat uninformed.
im probably not going to export if it gets 'out of RGB' and incurs quality loss if im wanting to reedit the material. so DI is digital intermediate i take it.. cineform is a lossless codec,? why cant i just use ut or lagarith to export and then work with that material, that would be easier no,?
maybe i will need cineform, so it converts whatever input to a cineform file? to be worked in and outputs to a lossless cineform format that i can then convert/encode to whatever format, container i want..
seems both are effectively the same thing, considering this using lagarith and ut are the better option, considering new pc etc, are there some guides or some places i can start to look at regarding how to use these codecs with premiere..
i feel like , as i am, enveloping myself into a slow progressive understanding of a field without the right knowledge or direction. i dont really know what im doing, dont really know how to proceed from here, i am undertaking this with the hope to perhaps work in the field. i have a lot of time in the next couple of months to really get involved with this on a daily basis but need a lossless workflow to be able to do so, im almost there, but at this point im still going to need to learn how to put a story together essentially, an entirely new field in of itself, where do i turn to to begin to undertake a process good enough to be able to put this together. this is a little offtopic maybe i should repost this elsewhere.. , at this point it seems i would need to mostly rough cut the story i have in mind, and take it to professional editors to assist me with the process.Last edited by krohm; 24th Jun 2011 at 17:58.

This is the way I would do it. If you only need 1min clip from a 2hr movie , why import the 2hr movie ? It will take ages conforming audio that you're not even going to use.

Lagarith is very slow to edit. It's not an editing format. It's an "archiving" format. Use Ut Video Codec, it's easily the fastest multithreaded lossless codec, faster than huffyuv . Lagarith is more compressed (smaller filesizes) . In general, lossless codecs aren't meant for editing - you don't get faster than realtime performance, scrubbing is slow as molasses. UT is the only one that can with HD footage, if you have a fast computer

If you 've never edited before, start looking at tutorials. Youtube or lynda.com has some beginner tutorial series -
did the lynda tutorials for cs5, did 20 out of the 25 or whatever, so yea im somewhat confident i can put some nice scenes together with the material i have, and storyboard it somewhat, but still im completely shooting in the dark, dont know where to turn read a lot of websites they all seem to be talking about filming etc, not sure how to actually put this together the creation of it, anyways ill look into that further myself that was more a side note.
thanks pdr with my goals of the way in which i want to approach this. seems like new pc + ut = project underway.. -
Yes, if you get the editing mechanics down, then you can actually work on the storytelling part.
But there are so many different "styles" and ways to do convey your message and a lot of it is subjective - there is no "right" way to do it. e.g. Things like type of transitions chosen, grading can affect the mood of the piece. For full control, you need to do the original shooting as well , and plan this FAR in advance - because you are already limited in the way you tell your story, if you use a preshot asset like a retail blu-ray. -
