Via google I saw some stuff on this forum that discusses mp4 in relation to HD. Is mp4 a HD file playable on Blue ray players only? Is MP4 as high a quality as AVCHD? The reason I asked is I thought mp4 was a less quality method for getting stuff on Youtube using less memory. Have a nice day.

Hope to see you

[doyal gudgel] "Is mp4 a HD file playable on Blue ray players only?"
No, MP4 files are mostly use for HD web video. Blu-ray players use M2TS, M2V, or AVC files.
[doyal gudgel] "Is MP4 as high a quality as AVCHD?"
It can be. AVCHD is a subset of the MPEG4 specification. So AVCHD is MP4 but MP4 can contain formats that are not AVCHD. As for quality, they are the same quality at the same profile, resolution, and bit-rate because they are both MPEG4 video.
[doyal gudgel] "The reason I asked is I thought mp4 was a less quality method for getting stuff on Youtube using less memory."
You are correct that MP4 is a popular file format for Internet video and that AVCHD (.M2TS) is a compatible format for Blu-ray but they are both MPEG4 video and can produce the same quality or different quality videos. Since AVCHD is a subset of MPEG4, it has more limited parameters to choose from.

OK, sounds great. I made a svchd DVD with vegas 9 platium off some material right off a HD ccamcorder and it was fantastic. It had to be SVCHD as it would not play on a standard DVD. Better than lots of BD movies. Some movies look like they aren't the quality especially what you might find on demo TV's in stores. The camcorder saves in MPS files. Vegas rendered this and made a svchd disk that would play only on BD. Now I look if I can render in AVCHD and cant find anything here in Vegas that says MPS, or SVCHD. Looking at the specs every one is a max of 720x480. DVD quality of course. or less. I am willing to spring for an improved version or even a pro version if I have to do that. That one certainly looked like HD that came off the camcorder. Boil it down to this Can I squeeze out any more quality on disks with HD from this material? The answer is in did I get all possible quality when rendering it 720x480 resolution? It would really be nice to clear this up.

I believe I saw where the DVD from from the camcorder files were 1080. The AVC (mp4 ) file in vegas was only 320x?.

OK, So better quality is done by how? Faster bit-rate? Is anything bigger than 720x480 a blue ray or maybe a HD? I never looked into it but suppose a DVD is standard 720x480.

Windows 7 DVD maker will make a DVD up to 150 minutes long. I never looked into the VEGAS 9 Platimum I have but is will make a DVD only about 125 minutes on account of bitrate or something I suppose. I suppose anything longer than this exceeds the capacity of the disk and vegas will not import it into the program. At least trying to import another disk after already importing a first one wont work.

Your comments on the above questions would be appreciated.

[doyal gudgel] "OK, So better quality is done by how? Faster bit-rate?"
Yes, increasing the bit-rate will increase the quality. Also using higher profiles will increase the quality. MPEG4 is a very complicated specification with multiple profiles and understanding it is not easy. That's why it's best to use the templates that Sony provides and not modify anything except the bit-rate to get the file size and quality you are looking for.
[doyal gudgel] "Is anything bigger than 720x480 a blue ray or maybe a HD? I never looked into it but suppose a DVD is standard 720x480."
NTSC DVD maxes out at 720x480. Blu-ray gives you full 1920x1080 HD.
[doyal gudgel] "Windows 7 DVD maker will make a DVD up to 150 minutes long.

You can change the bit-rate in Movie Studio HD Platinum 11.0 to be anything you want. I don't know if your version of Movie Studio allows this. This is why it's always good to keep your software up to date. Look under Project | Render As... and see if it will let you modify the MPEG2 DVD template to change the bit-rate.

The current version of Movie Studio HD is 11.0. You are two versions behind on 9.0. I think you will find a few more rendering options by upgrading your software to match the video files you are trying to work with. I would download the trial of Movie Studio HD 11.0 and see if it has the rendering options you need.

I would also recommend that you purchase a Blu-ray burner if you are interested in making Blu-ray discs. It makes no sense to burn AVCHD to DVD these days. That was popular several years ago when Blu-ray media cost $25 a disc and Blu-ray burners were $699. Now you can get a Blu-ray burner for $99 and discs for $1 so playing around with AVCHD on DVD not worth the trouble. Make a proper Blu-ray disc if you want HD.

OK, including BD is good. I have the software and can get the burner. My question is under what circumstances do I use it?
what is a good source to make a BD instead of a DVD? The obvious source of a HD camcorder is probably worth it. But what about the source of old mm film, 16mm film, and super VHS tape? Would there be any advantage to burn these sources in BD? Maybe also good photos used in a music or other video. What about the stuff I have already made and burnt on a DVD would it be to any advantage to burn it now on BD? Especially that question. I am past the stage of creating a lot of new material so the above questions are important to save myself a lot of useless work. It's wonderful to find someone with these answers and I wont have to spend hours trying to find the answer myself. Have a nice day.
