I originally started using PrE7 to capture video from VHS tapes. Then I started trying to include some mpeg's from various sources and I found PrE did some weird stuff or strange video. It seemed that PrE was trying to convert things inside of the program, but didn't like the input. The preset I had been using was the NTSC DV Camcorder 4:3 Standard which recognized my Pyro AV LInk analog converter, and the resulting video was AVI, no problem. I also have PrE9 which I have been experimenting with lately.
I also MISTAKENLY thought mpeg and vob were all lower field first (LFF) (which is what PrE uses? if I understand that correctly). In the process of analyzing video with GSpot I discovered Ihad a mix of things. The Video from my Sony Flash Memory Camcorder was upper field first (TFF). Some of the other mpeg's and vob's were also a mixed bag. So I can't use a combo of these things in the same Preset. If I have upper field video I would have to start another project, use the Flash Memory 4:3 preset, let PrE swap fields in the program, and export the video as AVI. Then re-import the video into the other project to be able to use along with the VHS video. Or some version of that. Or use external video conversion such as MPEG Streamclip. No matter how I do it, I have to uncompress the mpeg or vob video, edit it through PrE, and then recompress it again to make a DVD.
Now to my question. If I use the correct preset when I start a project, (one for lower field mpeg or vob, and another project for the upper field mpeg or vob), how good of a job of converting the video to AVI in the program is PrE going to do? Is it going to reinterpret what is missing and essentially build as good an AVI as an external converter (such as MPEG Streamclip), or will the external converters do a better job. The interest being to get the best quality. I know you are going to say there will probably be quality lost either way. The other option you might say is convert the VHS to mpeg, and export it to another program (which is designed to use mpeg and vob) along with the existing mpeg's and vob's I already have. That would defeat the purpose of having Premiere Elements, but is a possibility.
I also (per Steve's post 415317 "What tools can I use to convert my video to DV-AVI") downloaded WMM 2.6 and ran some video through it. The AVI that it produced was Type 1 which brings up another question. What does PrE do with type 1 AVI when combined with type 2 in the same project? More conversion? I understand that type 1 has to be split to become Type 2. So do I skip type 1 and use converters which spit out type 2? All of these back and forth conversions are cpu intensive. Also of note from Steve's post was the Super video converter. Version 38 was the one being used when the post was written. It appears that the latest verisions of Super are adware and guys were not pleased with that, so I bypassed that conversion option. You can do some reseach on the internet and read the feedback.
I realize my projects are simple compared to what some guys are trying to do, but I would like to find out what PrE converts the best, or what would be better conversion with an external source before inputting.
