i have an EasyCAP USB 2.0 Audio & Video Capture Adapter that i'm trying to find good software for capturing/encoding on the fly that also allows video/audio preview for use when i'm not actually recording.

at the moment i'm using Ulead mediastudio 8.0 but it won't let me select the audio format to encode to while recording, producing files with bloated audio size.

i've tried using sony vegas 8.0b to capture but it doesn't seem to like working with the adapter and virtualdub's video preview is out of sync with the audio preview that it produces along with the fact that the last uncompressed or compressed captures i tried with virtualdub ended up crashing the computer.

this is all when i'm trying to capture at 720x576. at 352x288 it captures at good speed but often low quality and i'm trying to capture good quality video. the only codec that compresses on-the-fly with good fps at 720x576 is ffdshow but i can't find a config that doesn't produce blocky video. XViD produces good quality at a cost of jumpy video and uncompressed output produces files too impractical to use (5.20gb for 4mins of video is too unwieldy).

if i could tweak ffdshow to stop the blockiness, then the codec issue would be solved but would still leave the software used to capture as an issue.

Select huffyuv as the compressing codec in ffdshow. Leave all other settings at default and ensure YV12 mode is NOT checked.

This is a lossless codec so the file size will be large, but not nearly as large as uncompressed ARGB. Open the video in another program like VirtualDub and transcode it to something else like 2-pass Xvid video with 128kbps LAME MP3 stereo audio.

HCR: even if the virtualdub crash issue was a temporary one, i also use the capture card to play without recording and i stated it has an audio/video preview sync problem, making anything unplayable through the preview.

and i'll try the XViD suggestion as soon as i can (the a/v setup that outputs to both TV and video capture device at the same time is being used by my brother to play his wii right now)

edit -
Masta: i'll also test your ffdshow suggestion next time i can. i was hoping to avoid re-encoding but if i have to, i will.

Audio/Video sync issues can be fixed by going to Capture > Timing.

Since you have a USB capture device, check automatically disable resync. The settings I have selected under DirectShow options is what works for me. (I too have a USB capture device) You may need to turn off/on some of these settings until your issues go away.

HCR: the stuttering with XVid doesn't occur with your settings :). that's the codec sorted then.
Masta: still can't get it to sync up at all. i set it to your settings then tried various combinations of it and still nothing. the audio keeps on appearing a couple of seconds late no matter what. and the desync happens in both the preview and in the recording.

Start VirtualDub.

Go to File > Capture AVI

Go to Capture > Timing

BTW - The screenshot was taken from VirtualDub 1.8.8

If your question is in regards to your previous thread, then this will not fix anything for you.
