AVSEdit Cropping

[Nitro89]

that MPC method is the worst thing ever, the audio keeps moving around once I've already moved it, its impossible to use, I just want to fix my delay, how do I go about it?

[guns1inger]

MPC is simply to find out exactly what the delay is.

If you go back to my original post, you will see that I suggest you use this to

a. Confirm that the delay specified by DGIndex is correct, and then
b. Confirm that DelayCut has corrected the audio sync issue

If, after DelayCut, MPC shows no sync issues, you know that the problem with with Imago when you remux the audio and video.

[Nitro89]

there's a HUGE sync issue, once I demuxed it using DGIndex, the delay was 1320ms, but when I move the audio to this position (-1320 and +1320) its still way out of sync. Every time I move the audio and restart the video, the audio moves, I move the cursor from where I started the video without increasing and decreasing the delay, the audio moves yet again.

[manono]

I may not be understanding you correctly here, but you got the +/- thing working OK, following what jagabo did to turn it on? And when you use the + or - keys, you can see the delay at the bottom left of Media Player Classic? You can play the video while adjusting the delay, and that's why I didn't understand when you said, "Every time I move the audio and restart the video..." because you shouldn't have to restart the video. You should be adjusting the audio delay while the video is playing, and you should see the effects of the delay changes immediately. If you actually shut down and then restart MPC after setting the delay, the delay goes back to zero. But like I said, I may have misunderstood you.

And as I said earlier, if you do an improper decrypt, the delay that DGIndex gives to the audio might be incorrect. If this is Hairspray or some other new movie (please say which it is if it's not Hairspray), please tell us how you got it to the hard drive - which program you used.

[Nitro89]

wait, now that you said that I can adjust the delay during playback, its worked, thanks a lot, I was previously adjusting the audio, stopped the video and started from the beginning, so now, how do I fix the delay?

(It also doesn't help if you move the courser to anywhere on the video.)

[manono]

You fix the delay by following my instructions in an earlier post about how to use DelayCut correctly.

[Nitro89]

No, don't tick the "Fix" button. First find out the amount of the delay. guns1inger's method is one way. Fill in that same amount in the "Start" box of the "Delay" section of DelayCut. Leave everything else alone. Then "Process".

Do I tick the 'Original Length' option box?

I've now remuxed the video and audio, its all in sync, then, using AVSEdit, I trimmed and faded etc, the preview worked, but how do I save the final product (video, not script) onto my hard drive?

Note that I do not want to convert it, but just trim it, autocrop it but without converting it in any way.

[guns1inger]

AVSEdit should allow you to save your script as an avs file. You load this into you encoder and encode. You can't fade or crop video without encoding. Only simple trimming can be done without encoding. Avisynth produces uncompressed video, so everything done with avisynth must be re-encoded.

[Nitro89]

I don't understand how to encode, you mean I can use Avisynth to re-encode my video? how?

[Nitro89]

I tried looking for the option but can't seem to find any?

[jagabo]

AviSynth doesn't encode. It processes video then "frame serves" it to the encoder of your choice.

[Nitro89]

I tried opening an AVS file in SUPER and a few other progames compatible with it, but when I do, I gives me numerous options on converting my video such as FPS etc All I want is my AVS file to be processed exactly as it is.

[poisondeathray]

1) What final format container do you want? (i.e. mkv, avi, DVD etc...)
2) What codec compression do you want?

These choices affect your choice of encoder.

The script tells the encoder what to process, and how to process it. (e.g. you should already have fps settings in your script, no need to set it again)

[Nitro89]

I want an h264/AVC file for PSP.

If I do not want to change the fps on my video, do I need to write it in the script?

Also, my video is one file with audio and video, what do I write in the script to compress the audio in the video to 128kbps AAC?

[poisondeathray]

The script doesn't specify encoding settings for video, audio. That is determined usually by the encoder

PSP will only play certain files specifications (such as AVC level 3.0). You should really read up on this, otherwise it won't play.

Did you try ripbot264 as I suggested earlier? It makes it really easy, because it has a PSP encoding profile for compatibility. Since you already have a script, just open it up with ripbot264.

Select 128kbps for audio (not in the script, in the encoder). You may have to resize your video for it to work on a psp (should already be in your script, but you can do it in ripbot264 settings as well - it has a preset for PSP). Make sure you select Level 3.0 AVC (it's labelled PSP)

An alternative for an encoder for AVC is MeGUI, which also has a PSP profile if you download "Sharktooth's profiles", but the learning curve is very steep

DVDFab also has a PSP profile. 1 click DVD=> PSP.

[Nitro89]

I have tried ripbot264 but I also wanted to trim my video, add a fade in and out effect.

[poisondeathray]

You script "tells" the encoder that.

[Nitro89]

what encoder should I use if I only want it to output a trimmed video with a fade in and fade out effect, that way, I can let ripbot264 do the rest.

Also, I tried opening my AVS file using ripbot264, but it only encoded the script.

[poisondeathray]

The script is just a set of instructions; you are correct that the encoder does the rest. It's like a machine that needs instructions to work.

The settings like bitrate for video & audio, codecs used etc... are set in the encoder settings. The filters, resizing, cropping should be specified in your script.

Here is a sample script for trim & fade in/ fade out:

AVISource("D:\video\jack.avi")
part1=Trim(0,5000).FadeOut(150)
part2=Trim(5001,10000).Reverse.FadeOut(150).Revers e.FadeOut(150)
part3=Trim(10001,0).Reverse.FadeOut(150).Reverse
UnalignedSplice(part1,part2,part3)

If you want more suggestions on improving your script, check here:
https://forum.videohelp.com/topic99389.html

Any encoder will do. I only suggested ripbot264, because it is simple to use. If you script is "good", then just load it into any encoder, specify the video & audio settings and push encode!

Good luck

Did you specify trim, crop, fade in your script?

[Nitro89]

this is my script so far:

# VideoSource
DirectShowSource("C:\Documents and Settings\Mateusz\My Documents\My Videos\Hairspray (2007).mpg")

# Trim
Trim(400,152925)

# Autocrop
AutoCrop()

# FadeIn
FadeIn2(25)

# FadeOut
FadeOut2(152500)


How do I open the script in an encoder?

[jagabo]

The same way you open any video file. File -> Open

[poisondeathray]

How do I open the script in an encoder?

In ripbot264, click add, press "...", and point to the .avs file

In the Profile, select Level 3.0 SD, PSP

Configure your settings like bitrate

Press properties, under size, resize for "PSP"

Press preview script, if it looks OK, push OK.

Press done, press start.

*all this assumes that you have the correct filters. Were you able to preview the script correctly in MPC as suggested earlier? If not you are missing some codecs. Also did you rip "Hairspray" correctly? It is well know that copy protection on that DVD cause errors.

[Nitro89]

The script previewed correctly in MPC.

I am using QuEnc, I successfully entered in my AVS script, but the program asks me for the video bitrate (kbps), when I open the video up in WinDVD, the video bitrate is 7.000Mbps, but, GSpot says the video bitrate is 5189 ans 'Sys Bitrate: 10080 kb/s VBR'. I am not sure which one is which and whether QuEnc is asking me for kilobits or kilobytes?

Also, how do I know my video is interlaced?

Is 2 Pass Encoding necessary for this job?

At this moment I want my video as uncompressed as possible. I will leave the real encoding to ripbot264.

If you run mediainfo it will tell you if it's interlaced (view=> text)

I'm sorry, I don't understand why you are using quenc if your final goal is a file compatible with PSP? If you do this you are doing 2 lossy conversions = quality loss.

Why not just open your script up in ripbot264 and let it do all the work? (i.e. mpg => mp4 compatible with PSP)

[Nitro89]

Can I merge my script with the one in ripbot264?

To open my script, I go add, then '...' under the video title, yes?

Yes, but not "merged." Your script becomes the instruction set for ripbot264's encoding engine.

Step-by-step instructions are above.

[Nitro89]

is 2 Pass Encoding neccessary as my video is being converted from a HQ source? And isn't 2 Pass Encoding decreasing the quality of my video as it encodes it twice?

[poisondeathray]

2-pass encoding is not necessary, but will give you slightly better quality (but takes longer)

[Nitro89]

when I enter the script into ripbot264, when its 'gathering information', isn't it already encoding the video through the avs script, then, after that's complete, I choose the PSP settings, then it encodes again?

No. It takes a few seconds to parse the information. It's looking for what codecs are being used, demuxing the streams if necessary, and making adjustments. No encoding is done until you press start.
