Import via Elgato Video Capture or DV Passthru

I have a lot of old Hi8 and VHS tapes I want to transfer to digital. I have a DV camera with passthru so I could (and have) route the tape player through the camera into my iMac. However this is a little cumbersome. I was thinking of getting the new Elgato Video capture to simplify the process. The Elgato captures in MEPG-4.

The first question I have before I make the investment is: Should I expect any difference in quality of the picture or ease of use in iM09 between the two input formats?

Second, I will want to break up the large imported file into smaller clips. From the forum the best way seems to be to use MPEG Streamclip. If I do use that what format (if any) should convert the files to in MPEG Streamclip?

Thanks

24" iMac, Mac OS X (10.4.10)

I am not seeing any difference.

If you get the elGato, I would spend a few dollars more and get the ElGato EyeTV Hybrid. in addition to analog capture through USB, it also serves as a High Definition DVR so you can watch and record TV shows.

I have imported 8MM tapes through a Digital 8 passthrough into iMovie and also VHS tapes through the elGato.

With the ElGato EyeTV Hybrid, I import as MPEG2, then convert to Apple Intermediate Codec (and deinterlace) using MPEG Streamclip.

With the import through DV Digital 8, I also have to deinterlace using MPEG Streamclip. The quality is no better, but the files sizes are bigger.

The new ElGato you mention has the advantage of importing as h.264 rather than MPEG2. This should be fine for most purposes, but you can always convert the h.264 to AIC if you need to.

Appleman,

Thanks, Your response brings up two questions.
1) I looked at the elGato EyeTV hybrid and it only seems to have a RG-6 Cable Wire input, no RCA Video or S-Video inputs. How would I record with that? I must be missing something.

2) You and Steve Mullen have provided a lot of help but I'm still learning the ins and out of video codecs. I understand from Steve's book that for iM09 we need to deinterlace DV using Slipstream. Is MPEG-2 or h.264 interlaced also. Does iM09 accept h.264 but not MPEG-2? Is that why there is an advantage to importing as h.264? When an why would I want to convert h.264 to AIC which seems to have much bigger files? In most cases I plan to export my clips to iM09 and then the resulting movies to iDVD.

EyetV Hybrid has coax cable, RCA composite video, and S-Video inputs.

I don't have Steve's book, so you can ask him about anything he is recommending out of the mainstream.

iMovie can handle h.264, and it should be fine in 640x480. However, it is a highly compressed format. Apple Intermediate Codec basically "un-compresses" it into full frames. When you start trying to do long movies, or to do high definition in h.264, or to do effects like slow motion or image stabilization in h.264, you will run into trouble. You will get much better results in AIC.

My best advice. Use h.264, and if you are satisfied, stick with it. You can always go to AIC.

iMovie does not handle MPEG2 except for directly from a list of supported camcorders.

I saw about the cables after I sent the reply.

Am I correct in thinking that DV has minimal compression, MEPG-2 more compression and h.264 the most. I'm assuming that once compressed you don't recover the "lost" info. So converting DV to AIC should give a little better resolution (apart from the interlacing) than h.264. Yes? Whether I could tell the difference is anther thing.

I'm assuming that whether MPEG-2 or h.264 are interlaced or not is dependent upon the source. Apparently DV interlaces everything. What about analog directly to MPEG-2 or h.264? Is it interlaced or not?

Although it takes a while is seems like a good practice is to always convert to AIC.

I think that DV and AIC have minimal compression. They are in the same order of magnitude of compression.

MPEG2 is an interesting codec, in that the audio compression and the video compression are mixed up together in the stream. There is no audio portion of a frame. There are audio packets and then some video packets, and the player resolves these and puts them back in sync. It is used for digital TV and for DVD.

MPEG4 started out as a low bitrate codec, but has expanded over time to handle high bitrates and high quality.

For much better info, check Wikipedia.

Personally, I always convert to AIC - except for DV. But for certain applications, you can edit in h.264 and get good results. You will almost always share your final movie in h.264. THe only exception is if you are sending your project to DVD, in which case iDVD will accept AIC or DV or h.264. (and convert it to MPEG2). Another exception is if you are burning to BluRay via TOAST. In this case, you can share your movie in AIC, and let Toast do the conversion to h.264.

Actually if I look at the elGato site their products come in three flavors
1) EyeTY 250 Plus = DVR capability with outboard hardware encoder ($200)
2) EyeTV Hybrid = the 250 Plus without the outboard encoder. (encoding done on the Mac) ($150)
3)Video Capture = the 250 Plus - the DVR capability ($100)

Since having an outboard encoder is more important than the DVR (Got Tivo) #3 is a good fit fir me.

The outboard encoder is mainly useful for people with older Macs, like the G4 and G5. They don't have the processor speed or the graphics processor to do it inboard. With an Intel Mac, inboard works fine. You can import from the EyeTV Hybrid while surfing the web, word processing, etc. The only time you might want to have it outboard is if you wanted to be using another graphics intensive application at the same time you are importing. For example, if you wanted to render an iMovie Project at the same time you are importing to EyeTV. Most people don't need this.
