The Use of Force FILM.....

[Howdy]

Hello everyone,

I know a lot of you have the answer for this......so please help me.

The VCDs I made, using Sefy's guide looked great for the first 30 minutes, then they all started to get "blocky", especially when there are alot of movement. That's why I've tried Forced FILM to get better video, just like one of the guides I've read suggested. It did give me better video, but it also made the audio out of sync.....the longer I play the VCD, the more out of sync it gets. I guess because Forced Film only encodes at 23.97fps, therefore, the video file is shorter than the audio file.

I started by using Smart-Ripper, then DVD2AVI and TMPGEnc....any help would be greatly appreciated.

Regards,

Howdy

I believe when you use Forced Film you also must check the 3:2 pulldown option in TMPG. Also, you may want to force film in DVD2AVI when you frameserve it.

Using force film should not affect sync directly. It may have %20 less frames per second but its running %20 slower also so this effectively cancels each other out. Basically what I'm saying is that the playtime never changes so the audio and video should always match whether you force film or not, or IVTC or not. Also don't forget that when you play the vcd on your dvd player it will telecine it to 29.97fps anyway.

With that said, forced film still might be the indirect cause of your problem. My guess is that your dvd player is doing a poor job of a real time telecine. Some dvd players are better than others at this and some can't do it at all. If this is the case you are probably out of luck. You can either live with the sync drift, author shorter vcds, or attempt to custom sync each and every vcd. I think the best option is to stick to 29.97fps material or look into authoring svcds if your dvd player supports it.

I would first try using bbmpeg to multiplex your vcd rather than TMPGenc. I don't know of any particular compliancy problems with TMPGenc's mpeg1 multiplexing but nevertheless I think bbmpeg will guarantee compliancy.

Though not ideal, one possible solution to your problem might be to repeatedly pause and unpause the vcd when it starts to lose sync. On many players this seams to resync it.

spidey he is making a vcd not a svcd, the 3:2 pulldown is not an option.

Hello spidey and adam,

Thank you so much for your quick reply.

I think Adam hit it right on the nose, because when I play my VCD on different players, the problem doesn't seem as bad.....I have one of those inexpensive Philips DVD player that can play MP3 music as well....you get what you pay for !

Any suggestion on what brand and model of DVD player to buy?

Thanks again,

Howdy

Well I have heard of numerous problems with desync in Phillips players, even the high end ones. Personally if I had to recommend an all around player I would suggest a Pioneer. They seem to play vcds and svcds very well yet still have good dvd playback quailty.

But I wouldnt necessarily just buy a new player. I forgot to mention the possibility of upgrading the firmware on your Philips player. New firmwares often eliminate syncing and other problems, especially if your dvd player is an older model. You could try looking for firmware updates on the internet or you could contact Phillips directly.

Another thing to keep in mind is that telecining is not always done consistently - this is apparently especially true for anime, and in my experience ollder movies. If this is the case, using forcefilm may produce poor results compared to a manual IVTC.
