mpc cant skip throuh a camstudio lossless avi

[krohm]

im using mpc and when trying to play back a camstudio lossless avi i recorded with hypercam it doesnt allow me to skip through the video. it will only play if i let it play through...

it also doesnt playback in premiere.. so cant edit the video....

[transporterfan]

Try Pot Player. The scrubbing is super-fast.

[krohm]

want to solve the problem though, not use another player

just tried potplayer, doesnt work in that either

[krohm]

should i post this in screen recording ?

what codec should i use.. camstudio lossless seems to output decent sized files, as opposed to ut... but it doesnt play back, and cant be edited in adobe premiere....

[El Heggunte]

It seems the captured file was muxed improperly by Hypercam.
Try opening the AVI in VirtualDub, and then remux (select Direct Stream Copy for both video and audio).

Other muxers worth trying (if VirtualDub doesn't work): AVI-Mux GUI, ffmpeg.

As for the capture codecs... I still have and prefer Camstudio 1.0 to the most recent version.
But HuffYUV is another decent option too.

[krohm]

dont want the massive massive files re huffyuv or ut...

just want to be able to have smooth playback that i can scrub through and be able to load into premiere and edit...

dont want to have to vdub everytime i want to look at my vid..

how can mpc not be able to playback a camstudio recorded codec ??

[El Heggunte]

As I tried to say, probably the source of the problem is in Hypercam itself.

If you don't want to use a different video capture application, or an older (but functional and bug-free) version of the same codec, or even worse, you don't even want to check if my hypothesis is right or is wrong,
well, good-luck to you.

[krohm]

they're all like that, its an mpc playback issue with the codec.. not hypercam

[krohm]

bump ^

[transporterfan]

Try loading into MPEG Streamclip and saving it off again.
It's possible hypercam is corrupting somehow or dropping frames so the sync is disrupted.
Streamclip will either cure it or choke on it. If it can't load it at all then it's probably beyond repair.

[krohm]

but it does it on every single file.. so it cant be hypercam its clearly mpc ?? i dloaded the program, opened the file and resaved it and doesnt play audio or video and is a way smaller file

[transporterfan]

If it does it on every single file then it is more likely to be hypercam than anything else.
Try reducing the capture rate (if it can be user set). You don't specify your system specs or capture rate.
If possible, post a 10 second clip and a MediaInfo report.

[krohm]

it isnt hypercam, as ut works.. even if the files are 100gb.. it records fine and i can scrub it in media player.. with the same settings...

i have it set to record and playback at 30fps and keyframes at 100...

i just want smooth recording of my desktop... what should i be using

the files playback fine.. but i cant fast forward/load them into premiere...

should i be using a diff software recording app... diff codec...

[transporterfan]

These settings work for this guy. We don't know yours. Follow it, maybe you will get your answer. Let me know.

this doesnt really have anything to do with my problem, this is about out of sync audio and video for camstudio and playback on some other piece of software.

can someone else assist with this, transporter fan is not really helping with anything at all regarding my problem, that is to say media player classic not scrubbing camstudio codec recorded video.. thats it. that is the problem. the video plays back, just doesnt scrub

[transporterfan]

1. the video is not about just audio sync problems but about getting the right settings for camstudio lossless codec (you missed that)
2. the video describes playback issues with camstudio lossless codec (you missed that too)
3. It has been known for a long time that many players (especially MPC) have problems playing back camstudio output (you have never bothered Googling for that).
4. I asked you for computer specs (you chose to miss that)
5. I asked you for a MediaInfo report and a sample (you chose to miss that)
6. El Heggunte has given you good advice (but you wont follow that)
7. if you are only recording your desktop you don't need a framerate higher than 25 (but I bet you wont change that)

In short there is no helping you. Bye, bye.

[krohm]

all of these points can be answered with the same problem, stated in the original message and re-iterated, its not playback that is the problem, its not settings, its media player not allowing it to scrub through/search..

1. which are fine because it plays back fine
2. i dont have playback issues
3. it plays back
4. computer specs arent the issue here, obv
5. media info.. i dont see how that has got anything to do with searching/scrubbing in mpc. its camstudio lossless codec, you want the res my monitor runs ?
6. El Heggunte suggested to use another player/codec/recording application, - thats not addressing the problem
7. ur right, i wont change that, but again, frame rate isnt the problem

8. ur an idiot

9. stated problem again - mpc not allowing search of an already recorded camstudio lossless avi, using hypercam, plays back, doesnt allow searching or scrubbing or loading into premiere...

any assistance that is actually relevant to stated problem would be appreciated

I don't use camstudio - but for MPC, maybe try ffdshow to decode instead of camstudio (enable camstudio in the directshow configuration) . You might have to play with codec priorities to make ffdshow preferred decoder

for premiere, I think you need 64bit version for camstudio codec (at least for CS5/6, CC7)

[krohm]

just uninstalled cccp and installed ffdshow and new mpc-hc, camtudio was already checked... still doesnt allow searching

what do you use for recording pdr.. what codec and what app...

[poisondeathray]

what do you use for recording pdr.. what codec and what app...

For screen recordings I typically use UT Video Codec, camtasia

[krohm]

then what you do with the massive files from there..,

[poisondeathray]

then what you do with the massive files from there..,

It depends what the goal is.

If it's something important , I keep the large files stored away on a HDD

I usually edit them then encode them to something smaller



If you don't need a lossless workflow use something lossy.

@poisondeathray:

Purely in the spirit of this forum I spent an hour investigating this.

Premiere wont import any file encoded with the Camstudio Lossless codec. Only audio shows up. I can't say if Adobe have changed anything lately or plan to. To capture properly and import into Premiere it is necessary to use something like UT Video codec (as you suggest) or Lagarith. El Heggunte was correct to advise a different codec, he was also right with his advice to copy out from VirtualDub as you will see later.

The problem has, in part, something to do with with the way Premiere processes P-Frames (from Camstudio?) and it is better to disable them altogether in Camstudio.

The real stumbling block though, is the RIFF tree architecture it creates. For some reason it produces garbage after the end of the Legacy Index. It is not a corrupt chunk, it's just completely invalid data possibly some internal method for storing variables. To get rid of this crap it means opening the AVI in VirtualDub and doing a straight copy of the video and audio streams to another AVI file. The new file will be an identical copy of the original but should be cleansed of the invalid data. This might enable MPC to play it properly and should negate the 'inconsistent file structure' message in Premiere. At the end of the day, Camstudio Lossless is good but produces files with a proprietary format incompatible with many mainstream editors and players.

Premiere also has a problem in that Camstudio codec captures confuse how it interprets the alpha channel. Clicking the clip and setting the flag to ignore the alpha channel should now ensure the proper frame is displayed.

It's easy enough to turn P-Frames off in Camstudio by forcing only key frames instead. This may well make the file longer, but hopefully makes it easier to edit.

Some of this old news but it may be useful to someone.

[krohm]

thanks transporter fan for the info.. will stop using the codec

will use lagarith and reencode.. gives 30gig files for an hour, but better than 50 for ut... they both load into premiere but only loads a few seconds or a few mins for both formats ... they are 30gb files ?? should repost this issue in another thread... ?

[El Heggunte]

Yes, please start a new topic, since you've got a different type of problem.
