Related to _program hangs when not using .MPG file formats.

[kstoj]

So I have similar problem as the one discussed in the related thread. I think I was able to overcome the issue but I still have few questions.

First here is the issue I experianced. I have a Canon Vixi HF100 HD video camera. I used the Roxio 2010 PRO to download bunch of video clips to my computer. They all where stored as .MTS files. Then I tried to use the VideWave to create the AVCHD disk out of this clips. I imported all of them and noticed that when I try to do anything the VW become nonresponsive ( lock -ups ) for long period of time and basically I can't do anything. I was able to identify that when I remove two clips everything is fine. So i did this steps: remove the "offending" clips, then try to add them one at the time at this point VW asks me to convert those to usable format, I did that and they were converted to .MPG files. After that I was able to edit and create my project. Questions I have out of these experiance are these:

1. How come some of the clips imported by the same Roxio program from the same camer where usable and some were not?

2. Which is the right format for the VW .MTS or .MPG files?

3. Is there any way to "manually" convert the Roxio captured .MTS to .MPG format?

4. Why Roxio has a problem with is own format?

5. Also will the Roxio work with M2ts format ( snce I didn't have too much luck doing it )?

6. Any way to prevent these type of issue in the future?

1: No idea, but some have reported it is usually the first clip on the camcorder so the solution was to keep one file on the camcorder. This may or may not for every one.

 

2: "right' format? Not sure what you mean. Videowave imports many types of files. Why it converts to MPG would have to ask Roxio. We're just users like yourself. I own several video editors and they all use 'proxy' files for hidef editing. This facilitates a quick preview and editing. Not sure how Roxio does it.

3: You can use any other shareware or commercial application to convert to MPG if you like.

4: PLease explain. Videowave and MyDVD both save their project files to respective formats. If you are talking about backward compatibility with previous versions, that is not always guaranteed with any application.

5: Yes, Videowave should import .m2t, .m2ts, .mts, .tp and .ts plus many more

6: Any what type of issue? Sometimes files are corrupt and can't be imported.

Thanks for the response.

Your #1 answer gives me much to think about, since both of the "bad" clips in my case were first clips in the camcorder's directory. So. it looks like the Roxio might have a problem.

 

#2. "Right" format. What I meant there is that Roxio imported the files from the camcorder as .MTS but could not handle it later on and it had to convert to .MPG. I understand that we all just users and not Roxio programmers but I was ( and still am ) hoping that someone might have some insides and maybe even someone from Roxio can respond.

 

#3. Do you know f I can do this conversion using Roxio tools?

 

#4. No. Not backward compalitibility, I'm bit upset about Roxio importing the files from my comcorder in specific format and later on complaing that this is bad format.

I'm programmer myself and that's why I find this interesting.

 

#5. I used the "native" camcorder tools to import the clips. They all were .M2TS format and the VW could not handle them, but I'm starting to thing that this might be again just specific ( first ) clips like in the case of import thru the Roxio tools.

 

#6 Again I was hoping for the answer to how I can prevent the Roxio tools from importing the file which later on can't be processed. I will look for the first clip in the camcorders directory from now on ( you #1 answer ).

 

Thanks again for the insites. Any other comment are sure welcome.

Sorry, but this isn't just a Roxio issue. I've read that other apps have a similar issue with 'first' clips so would appear (to me) , it's a camcorder issue or possibly a transfer issue.

 

Most video editors do NOT edit hidef files directly. They create a 'proxy' file. Videowave does edit MPEG 2 and DV AVI without creating video proxies. I think it still creates an audio proxy though.

 

Most of the newer camcorders use the AVC codec and very few editors can handle that format without creating a proxy file. Also be aware that the AVC codec compresses the video more and requires more CPU power than earlier formats to preview, edit and render - especially if it is AVCHD. For AVCHD, I highly recommend a Quad Core CPU.

Again thanks for the answers - they do make me feel better about my setup and about things I'm doing. My video camera does store data in AVCHD format, computer power is not an issue for me ( Dell XPS 9000, I7 Quad Core at 2.66 GH, 6GB of memory and it is screeming ).

Did you ever have a "first clip" problems in your HD editing experiance. What do you do in this case ( relay on software; like VideWave; to convert data or something else ).

I don't use AVCHD or a camcorder that records to memory/hard drive. I much prefer tape. I have a Canon HV20. So far, no problems plus I still have permanent back up after transfer to PC.
