HMC150 - The SD Memory Cards

bigox

Well-known member
I have questions about the HMC150 SD Memory cards.

Basics: I use a DVX100B and Edit on Sony Vegas Pro. My main projects are feature films.

I've heard the HMC150 referred to as the HD version of the DVX100b. So I'm assuming if you know the DVX100b, the HMC150 won't be difficult to get used to. Please correct me if I'm wrong about this.

Now, as far as the SD cards go, I have some questions and I guess I'm looking for comparisons to the HVX200A and it's p2 Card system because I've tried out the HVX200a and I was not happy with the red tape that accompanied the HVX200A in regards to editing the footage

1. The p2 cards are expensive
2. A 16 gb P2 card holds approximately 42 minutes of memory, which means if you're doing a long shoot (which I almost always do) there's a process of needing to offload in the field.
3. Offloading in the field requires a laptop with a special port, which none of mine have. So I have to get an adapter and at least 2 preferably 3 p2 cards to avoid delays while shooting.
4. When offloading the p2 cards to Vegas, you have to get a program called Raylight to act as a middle man.
5. The HD files are big and require a strong computer to deal with them or they are choppy.

So can someone give me the run down on using SD cards with the HMC150 in comparison to the HVX200a and it's p2 system?

Here are my specific questions:

I understand the SD cards are cheaper and carry a lot more memory space aka minutes per card than a p2 card. Is this accurate? And can you give me an idea as to cost for an SD Memory card for the HMC150 and how many minutes they hold?

Do you need a special port to offload the SD Memory Cards in the field? Or are the cards cheap enough and hold enough memory(MINUTES) that I won't need to offload in the field, but can rather just capture from the camera later on, much like what is done with tapes with the DVX. (THIS IS WHAT I'M HOPING FOR)

How long does it take to offload the SD Memory card? Is it real time like a DVX tape or much faster?

Do you need the Raylight program for to get this on Sony Vegas as well, like you do with the HVX?

I'm assuming that since we're still dealing with HD footage, a strong computer is still necessary, just as it is with the HVX200a. Does that pretty much hold true or is there a difference between the HMC150 & HVX200a in regards to that? Any specs on processor and ram minimums to deal deal with the HD footage?

And before anyone says anything about it, I have researched a lot of this already using search. I always do before asking questions, but most of these questions are just touched on in most of the topics and not answered clearly and directly, thus is why I'm asking for specific answers to specific questions to get a better understanding about the HMC150 and it's SD Memory Card system.

Thanks everyone!
 
To answer a few of your questions:
P2 vs SD isn't a straight 1:1 comparison. They both will store the same amount of DATA - what is largely different between the HVX200 and the HMC150 are their recording formats, and their resolutions. The HVX200 records about 90 minutes of 720p/24PN DVCProHD (960x720 pixels stretched to 1280x720) on a single 32GB P2 card. The HMC150 records about 3 hours of 1080p/24PN AVCHD (1920x1080 native) on a single SD card. The HVX200's codec is "heavier" - it uses up more card space per unit of time because it stores more information (4:2:2 color), though it is a lower resolution. The HMC150's codec is lighter - it uses up less card space per unit of time because it stores less color information (4:2:0 color), and it is more heavily compressed (though the results in my professional opinion are still fantastic).

SD cards are cheap enough that I bring more than enough with me to a shoot to cover the event's runtime x2, and I back up on-site so that I have 2 copies in transport. A class 10 Sandisk 32GB SDHC card (3 hours of record time at 1080p/24PN on the HMC150) will only set you back about $80 from B&H. Any cheap USB or built-into-a-laptop SD card reader will read the SD card media just fine on Windows, Mac, or Linux (my field laptop for backups uses Ubuntu Linux). I wouldn't offload from the camera, as a USB card reader will only cost about $10-20 at any electronics store, and it'll save you wear 'n' tear hours on your camera. Transfer speeds are very quick from the card to the computer - much much faster than the actual length of recording!

Offload times vary depending on a few things: Computer's hard disk speed, SD card's "class" rating (Class 10 is much faster than Class 4 or Class 6). I find that I can move an hour's worth of footage in about 10-15 minutes under optimal conditions.

I can't help you with the Sony Vegas stuff, as I use Avid Media Composer, Adobe Premiere, and Final Cut Pro.

I can't help you much with hardware, but I can tell you that the faster a computer is, and the more RAM it has, the better. AVCHD can edit natively (meaning straight off the card, straight into your editing software drag 'n' drop style) in some editing programs - not sure about Vegas. If you have to transcode from AVCHD to another format before editing (I transcode from AVCHD to Avid DNxHD when using HMC150 footage in Avid and in Final Cut Pro), it may take as much as the actual runtime of the footage to transcode, and that's using my Mac Pro tower @ work with 16GB of RAM... This aspect of the HMC150 can sometimes suck if you're on a heavily time-crunched deadline (we had this one shoot recently where we filmed from 10 AM until 2 PM, and the client needed a rough edit for feedback by 8PM that night and final by noon the next day - the HMC150's footage edited natively in Premiere just fine, but if we only had Avid available, we wouldn't have been able to turn that around so fast), but it is something that you can certainly plan for with experience. Maybe others can recommend some hardware specs as a benchmark here.

I'd definitely get an HMC150 again - it's everything I liked about my HVX200 and used regularly, and it improved a few things that made me dislike my HVX200 (HMC150 has a wider lens on the wide end, HMC150 is much better in low light, control surfaces are designed to work well with 35mm adapters like my Letus Extreme, the HMC150 doesn't have an heavy tape drive in the grip - much lighter for a full day of shooting, and the HMC150 uses less expensive media that's widely available in the field in the event that you run out of media - good luck finding a P2 card at a nearby Best Buy when your crew is on location with only 90 minutes of card space left!)

Happy shooting, and enjoy your HMC150!
 
Regarding the Raylight issue, you'll need it. One of the guys in my shop needed it for his HMC 150. Its because, if I'm not mistaken, much like the HVX, the HMC records as an .MTS file...which has issues with Vegas if you're not using Raylight. (I'm a Premiere/After Effects guy myself. One of the guys in my shop is a Vegas user and he's using Raylight for his HMC)
 
No reason to use P2 unless you ALREADY have a P2 workflow...

GO SDHC and never look back.. HMC150 and the new AC130/160 are all using SDHC.
