What formats can be edited (Womble) without Reencoding?

[bvanderw]

In the Womble documentation, it states:

"No re-encoding when editing DVD-compliant MPEG2 captures from the latest USB/DVD capture boxes."

Is this true of VCD, SVCD, and long-play DVD formats as well?

What formats can be edited without loss of quality?

Those are all MPEGs. Yes, easy to "edit" with no re-encode (simple edits only).

Exactly how would you define a "simple edit"? I ask because i keep getting errors with womble and I want to know if I'm using it beyond it's limits?

Merge things, cut stuff out, add a fade in/out, etc. Simple things.

Merge things, cut stuff out, add a fade in/out,

These are exactly the things I'm trying to do but I keep getting errors.

i've sent Womble tech support e-mails but got no response, maybe you can help.

Cutting works most of the time. but I get massive pixelation at cut points some of the time.

Joining almost never works, it keeps getting A/V de-synch in the saved file.

Fade in/out has NEVER worked! Not once, it saves for like 20 minutes then outputs an empty file.

Obviously the program does not do these thing to you, so i was wondering if you had any idea WTF is going wrong with mine? Maybe even give some advice about how to fix it?

Your source is causing it. I get that sometimes too, but it's from things not sourced from commercial DVD or from my own captures. It's only on converted DIVX, etc. It does not like messy files.

Consider demuxing, running through RESTREAM (check all the "fix" options) and remux again. Go back to Womble and try again.

TMPGENC and CCE files have the most issues. Sometimes ATI MMC with odd IPB values.

Just my observations.

Thanks.

i think this might fix some my problems. but i still have some questions.

Actually i am useing commercial dvd's. what I'm working on is re-editing a store bought dvd movie, restoreing deleted scenes and such.

however in some cases to get the deleted scenes the same AR as the main movie I have used Auto GK to make an AVI with the correct AR the used Tmpegenc to covert it back to Mpeg2. Could this be the sorce problems your talking about? if so do you have a better way to correct the AR of a deleted scene?

I have converted the 2ch ac3 to 6ch on the deleted scene. would this cause any issues?

I mainly use tmpegenc for muxing would this cause issues with womble? Should i use womble's muxing instead?

Also i read your guide about how to avoid droped frames when captureing (womble has done this when saving a couple of times) does this advice apply to basic video editing?

when useing RESTREAM do i load both audio and video or just video?

Thank you again for your time and advice, if you can answer any of the above questions I would greatly appreciate it
