Re: telecide and y0/y1 usage

Can you give me a source sample that displays your issue that I can use to experiment with?
Huh? What exactly are you talking about? Force Film is unrelated to 4:2:0/4:2:2.MrVideo wrote:I need to look into the forcefilm option for 4:2:0 sources. That was not usable here, as the source was 4:2:2.
DGIndex just decodes and delivers frames. It is Decomb that needs to adapt to errors, and it does so. If fields are orphaned by losses, they are corrected by the postprocessing, assuming you have it enabled.MrVideo wrote: How tolerant is the software to 3:2 pulldown errors? By this I mean every now and then the equipment used to create the 29.97 tape will drop a frame. For example, the five frame pulldown pattern starts at 0 and ends at 4. Some where in the program, one of the frames is dropped, resulting in the pattern now being frames 4, 0, 1, 2, 3. Is that tolerated by dgindex, or not? telecide/decimate has no problem working with it.
People usually use a standard of 95%, but it really depends on where the non-3:2 stuff is. Usually if you get 95% it's due to interlaced credits at the end, but you have to check that. Formally, postprocessing with FieldDeinterlace() on a Force Film project can fix stuff anywhere, but if the percentage is too low you will get too many frames deinterlaced when they could be field-matched.Oh, and what percentage of film in the D2V/DGI output is needed before Force Film is viable?
You can't rely on just this figure. You might have pure interlaced material, which would give 0% but require deinterlacing rather than IVTC. Or it could be hybrid, which presents some dilemmas, such as deciding what output frame rate to target (i.e., whether to decimate). I'm sure you are aware of this, but I mention it for the record.EDIT: Nevermind. I just read the tutorial that you pointed to and the material I have doesn't get any higher than 88% film. Most of it is 0%. I'll just stick with telecide/decimate, which provide excellent results.
A possibility is that there is a combination of hard and soft pulldown. That is really common for anime. In such cases, you have to honor pulldown and IVTC externally, as you are doing.MrVideo wrote:I can see where it can come up with 88%. Because the majority of videos that I work with have no pulldown flags, it isn't worth modifying my zshell script to work with so few files, considering that telecide/decimate is doing such a perfect job dealing with all that I throw at it (other than the repeat frame stuff).
Great to hear and thank you for your interest in my tools.That is great software. I really like it. It gets constant use.
