HD problem

[snapper8v]

Hello,
I have recently purchased a Go Pro HD Hero camera http://www.goprocamera.com/products/hd- ... camera.php but when editing the files in VS X2, I receive the message "Unable to open file, file mismatch" message. The camera records in "MPEG4 (.mp4) files using h.264 compression".

I have posted up a similar question yesterday entitled "File mismatch message" and Ron P replied saying:-

"The File format Mismatch error generally is due to trying to insert a photo when using the insert video command, or insert a video file using the insert image command. You should be able to insert an MP4 video file into VS. However I have on an occasion found MP4 files that I had to recode to get VS to accept it. There are so many variables of codecs, so there will be some that the program throws fits over.

I done some checking and found that while VS Pro X2 refused to open some of my YouTube downloads that were mp4 using the h.264 codec, I could insert them with VS X3. So there are some problems with MP4 files and VS X2.."

I have used AVS conversion software to convert the files from MP4 to MPEG and can now edit them, but I seem to have lost the HD effect!

I've just tried a different way to import the files (I had transferred them from the memory card onto the PC). I have now tried to capture the clips via import from mobile device, selected the memory card, then the file and..........................."the file XXXX is an invalid file format"

This is quite frustrating, can somebody please help me as I think I'm doing something wrong? TheVS X2 box states that I can capture high-definition video in HDV, so is it me??? Many thanks.

What are you doing with the final video? If your making a Blu-Ray, you'll want to maintain the maximum quality. If you're making a DVD, DVDs are not HD anyway... If your'e uploading to YouTube, you can keep the HD resolution but bitrate limitations will limit the overall quality.

I assume you converted to MPEG-2... I don't have AVS, but there is probably a setting for resolution (i.e. 1920x1080, etc.) Choose the same resolution as your original input file, and you'll maintain HD. But, since MPEG-2 is not as efficient as MPEG-4, you'll need to use a higher bitrate than the original to maintain the same quality. (With a higher bitrate, you'll have a bigger file.) And, there is always some quality loss when making a conversion.

HDV is not a general term, it's a particular format that's not as compressed as any of the MPEG versions. If AVS can convert to HDV that would be great! You'll have a bigger file, but the least-compressed formats are the most trouble-free. It's best if you can edit in HDV and then compress to your final desired format as the final step.

... ummm! HDV is high definition mpeg-2, and not some high def version of SD DV/AVI... That being said, it is definitely easier to edit and otherwise manipulate than mp4/h.264...

Thanks... I'd forgotten what the underlying format was...

Hi Lawrence

Importing video uses the same process as importing a still image from a camera.
OK
Capture/import your video files from your camera to your pc using the camera’s software.
OR--- if the camera records to memory stick/hard drive then you should be able to drag and drop the files from camera to a folder on the PC,
the camera acting as a removable drive…

Now open Video Studio,
Using X3 make sure that Smart Proxy is enabled, Settings -- Smart Proxy this will improve editing when using High Definition video.
Now right click the timeline and select “Insert Video”, browse your hard drive for your video files.
Smart Proxy files should be created, be patient, view the Proxy Manager.

Do you have any problems with this process................

Using High Definition video requires a fast efficient PC. You do not show any details of your pc’s spec’, please update your details via your profile.

Thanks for the replies, it's now sorted.

I spoke to the very nice people at Corel;, and they advised me to download the trial version of X3, and it works .

I'm not too sure whether I'll purchase the full version or choose Nero10, but I'm a happier person now. Thanks.
